!!! warning "The `°F` in your lambda must match the `°F` in your select"

The lambda comparisons below check `id(temp_unit).state == "°F"`. That string comparison is byte-exact. If the `°` character in your select options came from a different keyboard layout than the one in the lambda (some layouts produce U+00B0 DEGREE SIGN, others produce U+02DA RING ABOVE, which looks identical), the comparison silently always returns false and °F mode never triggers. Copy-paste the `°` from one place to the other to be safe, or change the select options and the lambda comparisons to plain `"C"` / `"F"`.
